Edit PO through View Order details in PO Approval form. This would be helpful if the user who is authorizing the PO wants to make edits while approving the PO. As per the current structure he will have to simultaneously open the PO form to make dits and so consumes more time.
When we move the transaction to the web, we shall give the approval option from the list view of the transaction itself. So if required, you will be able to double click and modify the same.
As of now, we are marking this idea as "Will not implement" because this will be available as the default feature once the transaction gets migrated to Ginesys Web.
